The decision to sack them from the party was taken by the national disciplinary committee which said as it was not satisfied with the response it got to the show-cause notice.

"The party's national disciplinary committee has taken a decision to expel Prashant Bhusan, Yogendra Yadav, Anand Kumar and Ajit Jha. They were expelled for gross indiscipline, anti-party activities and violation of code of conduct of the party," said party spokesperson Deepak Bajpai.

AAP crisis: Bhushan accuses Pankaj Gupta of accepting Rs 2 crore donation from shell companies

The rebels were given show-cause notice on April 17 to explain the reason for organising 'Swaraj Samwad'. Bhushan was charged with working for party's defeat in the Delhi assembly polls. He was also charged with supporting AWAM, a break away group of the party.

Three of them responded to the notice except Jha.

In their response to the notice, the rebels on Monday accused party chief Arvind Kejriwal of "gross violation" of its constitution and attacked two members of its disciplinary panel for allegedly doing a "planted" story and accepting donations from dubious firms.

Responding to show-cause notices issued by AAP's National Disciplinary Committee (NDC), Bhushan and Yadav questioned its locus standi for seeking their reply, saying the panel was formed after the "illegal" and "unconstitutional" meeting of the party's National Council on March 28.
